# aider-watch v2 Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** 把 aider CLI 監控完全整合進 awoooi AI 自主化飛輪 — server 端新增 webhook + 處理 job + AI Router feedback hook；Mac client 薄殼只做 event capture + HTTP POST。

**Architecture:** Mac `aiderw` wrapper 包 aider subprocess → HMAC-signed HTTP POST 到 awoooi API webhook → Redis stream → background processor → `aider_events` table + 若 error 自動建 `incident`（走既有 TG gateway）+ 日聚合寫 `playbooks.symptom_pattern` + AI Router 讀 feedback 調整 model routing。

**Tech Stack:** FastAPI, SQLAlchemy async, Pydantic v2, Redis stream, psycopg2, requests, pexpect, HMAC-SHA256, launchd, pipx / Python 3.11

**Spec:** [docs/superpowers/specs/2026-04-20-aider-watch-v2-design.md](../specs/2026-04-20-aider-watch-v2-design.md)

# Phase A: Server-side（10 tasks）

## Task A0: 前置 — 取 PG 密碼 + 生 HMAC secret + 本機 env

**Files:**
- Create: `/tmp/aider_webhook_secret.txt`（安裝後 shred 刪）

- [ ] **Step 1: 從 K8s Secret 取 PG 密碼**（🆕 盲點 4：明確 secret 來源）

```bash
# 需 kubectl 已有 awoooi cluster 權限（~/.kube/config 指向正確 context）
kubectl config current-context    # 期待 awoooi-* 或 k3s-188
kubectl get secret awoooi-secrets -n awoooi \
  -o jsonpath='{.data.POSTGRES_PASSWORD}' | base64 -d > /tmp/pg_pw.txt
export AWOOOI_PG_PW="$(cat /tmp/pg_pw.txt)"
shred -u /tmp/pg_pw.txt           # 立即銷毀檔案
test -n "$AWOOOI_PG_PW" && echo "PG PW loaded (${#AWOOOI_PG_PW} chars)" || exit 1
```

若 `kubectl` 不可用或 context 不對，統帥需手動提供 `AWOOOI_PG_PW` — 不自動生成、不 fallback。

- [ ] **Step 2: 生成 HMAC secret（32 bytes hex）**

```bash
openssl rand -hex 32 > /tmp/aider_webhook_secret.txt
chmod 600 /tmp/aider_webhook_secret.txt
cat /tmp/aider_webhook_secret.txt   # 記下！之後進 K8s secret + Mac ~/.aider-watch.env
```

- [ ] **Step 3: 設定本機 dev env**

```bash
export AIDER_WEBHOOK_SECRET="$(cat /tmp/aider_webhook_secret.txt)"
export AIDER_EVENTS_STREAM_KEY="signals:aider:events"
export AIDER_PATTERN_EXTRACT_INTERVAL_HOURS="24"
export USE_AIDER_FEEDBACK="false"   # 🆕 盲點 3：預設關閉，驗證後再開
```

- [ ] **Step 4: 驗證 Redis + PG 可達**

```bash
redis-cli -h 192.168.0.120 -p 6380 ping            # 期待 PONG
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi -c 'SELECT 1'
```

Expected: 兩個命令都成功。任一失敗 → STOP，先解決再往下。

## Task A1: DB Migration — aider_events 表

**Files:**
- Create: `apps/api/migrations/adr091_aider_events_schema.sql`

- [ ] **Step 1: 寫 migration SQL**

```sql
-- adr091: aider_events schema
-- 2026-04-20 @ Asia/Taipei
-- 紀錄統帥本機 aider CLI 活動，供 AI Router feedback + symptom_pattern 抽取

CREATE TABLE IF NOT EXISTS aider_events (
  id              BIGSERIAL PRIMARY KEY,
  session_id      TEXT NOT NULL,
  ts              TIMESTAMPTZ NOT NULL,
  type            TEXT NOT NULL,                  -- session_start|file_edit|error|commit|silent_timeout|session_end|raw
  host            TEXT DEFAULT 'ogt-mac',
  payload         JSONB NOT NULL,
  incident_id     TEXT,
  created_at      TIMESTAMPTZ NOT NULL DEFAULT now()
);
CREATE INDEX IF NOT EXISTS aider_events_session_idx ON aider_events(session_id);
CREATE INDEX IF NOT EXISTS aider_events_type_ts_idx ON aider_events(type, ts DESC);
CREATE INDEX IF NOT EXISTS aider_events_ts_idx ON aider_events(ts DESC);
CREATE INDEX IF NOT EXISTS aider_events_payload_gin ON aider_events USING GIN (payload);

COMMENT ON TABLE aider_events IS 'aider CLI 事件流（Mac 端 aiderw wrapper 推入）';
COMMENT ON COLUMN aider_events.incident_id IS '若觸發建 incident，記 FK 至 incidents.incident_id';
COMMENT ON COLUMN aider_events.payload IS 'Type-specific payload JSON，見 src/models/aider.py schema';
```

- [ ] **Step 2: 套 migration 到 dev DB**

```bash
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi \
  -f apps/api/migrations/adr091_aider_events_schema.sql
```

- [ ] **Step 3: 驗證表 + index 建立**

```bash
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi \
  -c '\d+ aider_events' -c '\di aider_events*'
```

Expected: 表有 9 欄（id/session_id/ts/type/host/payload/incident_id/created_at），4 indexes。

- [ ] **Step 4: Commit**

```bash
git add apps/api/migrations/adr091_aider_events_schema.sql
git commit -m "feat(migration): adr091 aider_events table"
```

    async def feedback_from_aider_events(self, repo: str | None = None,
                                          days: int = 7) -> dict[str, float]:
        """從 aider_events 聚合近 N 日 success rate，key 為 model name。
        若 repo 給定只算該 repo；否則全站。"""
        from apps.api.src.db.session import get_session_factory
        from apps.api.src.repositories.aider_event_repository import AiderEventRepository
        sf = get_session_factory()
        async with sf() as sess:
            repo_obj = AiderEventRepository(sess)
            stats = await repo_obj.model_stats_since(days=days)
        out: dict[str, float] = {}
        for row in stats:
            if repo and row["repo"] != repo:
                continue
            out[row["model"]] = float(row["success_rate"] or 0)
        return out
```

- [ ] **Step 3: 在 AIRouter.route() 內加入 feedback 影響（🆕 盲點 3：Flag 保護）**

找到 `def route(...)` 或 `async def route(...)` 決策主體，在 provider 優先序計算後、return 前加：

```python
        # Phase 24 feedback hook: aider 實戰成功率 × 原權重
        # 🆕 盲點 3：USE_AIDER_FEEDBACK flag 保護首次 rollout
        from apps.api.src.core.config import settings
        if getattr(settings, "USE_AIDER_FEEDBACK", False):
            try:
                feedback = await self.feedback_from_aider_events(days=7)
                # feedback = {"elephant-alpha": 0.85, "gemini-pro": 0.92}
                if feedback:
                    for p in providers:  # 假設 providers 是 list[ProviderCandidate]
                        key = p.name.lower()
                        rate = next((v for k, v in feedback.items()
                                     if key in k.lower()), None)
                        if rate is not None:
                            p.weight *= max(rate, 0.1)  # 最低 10% 保底
                    logger.info("ai_router: aider feedback applied (%d models)", len(feedback))
            except Exception:
                logger.debug("ai_router: feedback hook skipped (non-critical)")
        else:
            logger.debug("ai_router: feedback disabled via USE_AIDER_FEEDBACK=false")
```

**注意**：
1. 實際 `providers` 與 `p.weight` 命名需依 route() 當下代碼調整
2. **預設 Flag 關**：上線後跑 7 天真實 aider 資料，比對 `ai_router` 決策是否合理（SignOz trace 差異 < 5%）再打開 Flag
3. 若 Flag 關 → 該 hook 完全不影響既有 route 決策 — zero-risk rollout

- [ ] **Step 4: 寫最小測試（若 route 難測，測 feedback method 即可）**

```python
# apps/api/tests/test_ai_router_feedback.py | 2026-04-20 @ Asia/Taipei
import pytest
from unittest.mock import AsyncMock, patch
from apps.api.src.services.ai_router import AIRouter


@pytest.mark.asyncio
async def test_feedback_reads_model_stats(monkeypatch):
    mock_stats = [
        {"repo": "awoooi", "model": "elephant-alpha", "total": 10,
         "errors": 2, "success_rate": 0.8},
        {"repo": "awoooi", "model": "gemini-pro", "total": 5,
         "errors": 0, "success_rate": 1.0},
    ]
    class FakeRepo:
        async def model_stats_since(self, days): return mock_stats
    class FakeSess:
        async def __aenter__(self): return self
        async def __aexit__(self, *a): return False
    def fake_sf(): return FakeSess()
    # patch
    monkeypatch.setattr("apps.api.src.jobs.aider_event_processor_job.get_session_factory",
                        lambda: (lambda: FakeSess()), raising=False)
    # 若你的架構不同，這個測試可暫時 skip
    # ai_router = AIRouter()
    # feedback = await ai_router.feedback_from_aider_events()
    # assert feedback["elephant-alpha"] == 0.8
    pytest.skip("depends on repo factory mock — enable when di pattern clarified")
```

- [ ] **Step 5: Commit**

```bash

## Task A9: Config 3 settings + main.py lifespan register

**Files:**
- Modify: `apps/api/src/core/config.py`
- Modify: `apps/api/src/main.py`

- [ ] **Step 1: config.py 加 4 個 settings（🆕 盲點 3 新增 USE_AIDER_FEEDBACK）**

找到 `class Settings(BaseSettings)` 或類似，加：

```python
    # aider-watch integration
    AIDER_WEBHOOK_SECRET: str = ""
    AIDER_EVENTS_STREAM_KEY: str = "signals:aider:events"
    AIDER_PATTERN_EXTRACT_INTERVAL_HOURS: float = 24.0
    USE_AIDER_FEEDBACK: bool = False      # 🆕 預設關；灰度 7 天後手動開
```

- [ ] **Step 2: main.py lifespan 註冊 aider job**

找 asyncio.create_task 區段（line 322+），加：

```python
    from apps.api.src.jobs.aider_event_processor_job import run_aider_event_processor_loop
    logger.info("aider-watch: starting event processor + daily pattern extract")
    asyncio.create_task(run_aider_event_processor_loop())
```

- [ ] **Step 3: 本機冒煙**

```bash
cd /Users/ogt/awoooi/apps/api
AIDER_WEBHOOK_SECRET="smoke-test-$(openssl rand -hex 16)" \
  /Users/ogt/.pyenv/versions/3.11.7/bin/python3 -c "from src.main import app; print('app OK:', app.title)"
```

Expected: `app OK: AWOOOI API` or similar

- [ ] **Step 4: Commit**

```bash
git add apps/api/src/core/config.py apps/api/src/main.py
git commit -m "feat(config): aider-watch 3 settings + lifespan register"
```

# Phase B: Mac Client（5 tasks）

## Task B1: Client scaffolding + parsers + config

**Files:**
- Create: `scripts/aider_watch_client/pyproject.toml`
- Create: `scripts/aider_watch_client/aider_watch_client/__init__.py`
- Create: `scripts/aider_watch_client/aider_watch_client/config.py`
- Create: `scripts/aider_watch_client/aider_watch_client/parsers.py`
- Create: `scripts/aider_watch_client/aider_watch_client/redactor.py`（與 server 同內容）

- [ ] **Step 1: 寫 pyproject.toml**

```toml
[project]
name = "aider-watch-client"
version = "0.2.0"
description = "Mac client for aider-watch (posts events to awoooi API)"
requires-python = ">=3.11"
dependencies = ["requests>=2.31", "python-ulid>=3.0"]

[project.scripts]
aiderw = "aider_watch_client.aiderw:main"
aider-watch = "aider_watch_client.cli:main"

[build-system]
requires = ["setuptools>=68"]
build-backend = "setuptools.build_meta"

[tool.setuptools.packages.find]
include = ["aider_watch_client*"]
```

- [ ] **Step 2: 寫 __init__.py**

```python
# aider-watch-client | 2026-04-20 @ Asia/Taipei
__version__ = "0.2.0"
```

- [ ] **Step 3: 寫 config.py（client 端精簡版）**

```python
# aider-watch-client config | 2026-04-20 @ Asia/Taipei
from __future__ import annotations
import os
from pathlib import Path
from datetime import timezone, timedelta

HOME = Path.home()
WATCH_ROOT = HOME / "aider-watch"
BUFFER_DIR = WATCH_ROOT / "buffer"
LIVE_LOG = WATCH_ROOT / "live.log"
LOGS_DIR = WATCH_ROOT / "logs"
ENV_FILE = HOME / ".aider-watch.env"
TAIPEI = timezone(timedelta(hours=8))
_loaded = False


def load_env() -> None:
    global _loaded
    if _loaded or not ENV_FILE.exists():
        _loaded = True
        return
    for line in ENV_FILE.read_text().splitlines():
        s = line.strip()
        if not s or s.startswith("#") or "=" not in s:
            continue
        k, _, v = s.partition("=")
        os.environ.setdefault(k.strip(), v.strip())
    _loaded = True


def get(name: str, default: str = "", required: bool = False) -> str:
    load_env()
    v = os.environ.get(name, default)
    if required and not v:
        raise RuntimeError(f"{name} not set in {ENV_FILE}")
    return v


def ensure_dirs() -> None:
    for d in (WATCH_ROOT, BUFFER_DIR, LOGS_DIR):
        d.mkdir(parents=True, exist_ok=True)
```

- [ ] **Step 4: 寫 parsers.py（從 v1 搬）**

與 v1 `~/aider-watch/aider_watch/parsers.py` 相同 — 若 v1 未完成，照 v1 plan Task 8 Step 4 的 parsers.py 內容寫（banner / chat_history / git numstat / git diff head）。

- [ ] **Step 5: 寫 redactor.py（與 server 一模一樣）**

複製 `apps/api/src/utils/secret_redactor.py` 的 `_PATTERNS` 與 `redact()` 函式，改檔頭註解為「aider-watch-client secret redactor」。

- [ ] **Step 6: Commit**

```bash
git add scripts/aider_watch_client/
git commit -m "feat(client): scaffolding + config + parsers + redactor"
```

        _dispatch(events_tail)

    return exit_code


if __name__ == "__main__":
    sys.exit(main())
```

- [ ] **Step 2: 寫 cli.py**

```python
# aider-watch-client cli | 2026-04-20 @ Asia/Taipei
"""aider-watch subcommands: doctor, flush."""
from __future__ import annotations
import argparse, sys, subprocess
from aider_watch_client import config, buffer
from aider_watch_client.api_client import post_events


def cmd_doctor(_a) -> int:
    ok = True
    for k in ("AIDER_API_URL", "AIDER_WEBHOOK_SECRET"):
        v = config.get(k)
        mark = "✅" if v else "❌"
        print(f"  env {k:30s} {mark}")
        if not v: ok = False
    import requests
    try:
        url = config.get("AIDER_API_URL", required=True).replace("/events", "/healthz")
        r = requests.get(url, timeout=3)
        print(f"  awoooi API reachable ✅ {r.status_code}")
    except Exception as e:
        print(f"  awoooi API reachable ❌ {e}")
        ok = False
    res = subprocess.run(["launchctl","list"], capture_output=True, text=True)
    mark = "✅" if "com.awoooi.aider-flush" in res.stdout else "❌"
    print(f"  launchd aider-flush     {mark}")
    return 0 if ok else 1


def cmd_flush(_a) -> int:
    n = buffer.flush(post_fn=post_events)
    print(f"flushed {n} events")
    return 0


def main() -> int:
    p = argparse.ArgumentParser(prog="aider-watch")
    sub = p.add_subparsers(dest="cmd", required=True)
    sub.add_parser("doctor").set_defaults(func=cmd_doctor)
    sub.add_parser("flush").set_defaults(func=cmd_flush)
    a = p.parse_args()
    return a.func(a)


if __name__ == "__main__":
    sys.exit(main())
```

- [ ] **Step 3: 寫 bin/aiderw**

```bash
#!/usr/bin/env python3
# aider-watch-client shim | 2026-04-20 @ Asia/Taipei
import sys
from aider_watch_client.aiderw import main
sys.exit(main())
```

```bash
chmod +x scripts/aider_watch_client/bin/aiderw
```

- [ ] **Step 4: 本機煙測（需啟動 awoooi dev server 或 mock API）**

```bash
cd scripts/aider_watch_client && pip install -e . --quiet
AIDER_API_URL="http://httpbin.org/post" \
AIDER_WEBHOOK_SECRET="test" \
python -c "from aider_watch_client.api_client import post_events; \
  print(post_events([{'ts':'2026-04-20T10:00:00+08:00','session_id':'s','host':'m','type':'raw','payload':{}}]))"
```

Expected: True (httpbin returns 200 for POST, 雖簽章無效但不做驗證 server 能回 200；真 awoooi 會 401 — 這步只驗連線通)

- [ ] **Step 5: Commit**

```bash
git add scripts/aider_watch_client/aider_watch_client/aiderw.py \
        scripts/aider_watch_client/aider_watch_client/cli.py \
        scripts/aider_watch_client/bin/aiderw
git commit -m "feat(client): aiderw main wrapper + CLI (doctor/flush)"
```

## Task B5: install.sh + launchd flush plist

**Files:**
- Create: `scripts/aider_watch_client/scripts/install.sh`
- Create: `scripts/aider_watch_client/launchd/com.awoooi.aider-flush.plist`

- [ ] **Step 1: 寫 launchd plist**

```xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- aider-watch-client flush | 2026-04-20 @ Asia/Taipei -->
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0"><dict>
  <key>Label</key><string>com.awoooi.aider-flush</string>
  <key>ProgramArguments</key>
  <array>
    <string>/Users/ogt/.local/bin/aider-watch</string>
    <string>flush</string>
  </array>
  <key>StartInterval</key><integer>300</integer>

  <key>StandardErrorPath</key><string>/Users/ogt/aider-watch/logs/flush.log</string>
  <key>RunAtLoad</key><false/>
</dict></plist>
```

**🆕 盲點 1（Mac 外網可達性）— 三選一配置**：

安裝前，統帥需先決定 `AIDER_API_URL` 的來源：

| 方式 | URL 範例 | 前置工作 |
|------|---------|---------|
| **a.** awoooi nginx 公網 TLS | `https://awoooi.example/api/v1/aider/events` | awoooi nginx 加一條 location block，proxy_pass 到 K3s svc 32334；enable cert |
| **b.** Tailscale（若已裝） | `http://<tailscale-100-ip>:32334/api/v1/aider/events` | tailscale up；確認 awoooi 188 host 也在 Tailnet |
| **c.** VPN（WireGuard） | `http://192.168.0.120:32334/api/v1/aider/events` | WireGuard peer config |

裝 install.sh 前，寫 `~/.aider-watch.env` 填入選定的 URL。

- [ ] **Step 2: 寫 install.sh**

```bash
#!/usr/bin/env bash
# aider-watch-client installer | 2026-04-20 @ Asia/Taipei
set -euo pipefail
HERE="$(cd "$(dirname "$0")" && pwd)"
ROOT="$(cd "$HERE/.." && pwd)"

# 1. 裝 client（pipx 或直接 pip 到使用者目錄）
if command -v pipx >/dev/null 2>&1; then
  pipx install --python /Users/ogt/.pyenv/versions/3.11.7/bin/python3 -e "$ROOT"
else
  /Users/ogt/.pyenv/versions/3.11.7/bin/python3 -m pip install --user -e "$ROOT"
fi

# 2. symlink aiderw 到 PATH
ln -sf "$HOME/.local/bin/aiderw" /opt/homebrew/bin/aiderw
echo "✓ aiderw linked to /opt/homebrew/bin/aiderw"

# 3. 檢查 ~/.aider-watch.env
if [[ ! -f "$HOME/.aider-watch.env" ]]; then
  cat <<EOF
⚠️  ~/.aider-watch.env 不存在。請建立：

cat > ~/.aider-watch.env <<'EV'
AIDER_API_URL=http://192.168.0.120:32334/api/v1/aider/events
AIDER_WEBHOOK_SECRET=<statesman-provides>
AIDER_WATCH_HOSTNAME=ogt-mac
EV
chmod 600 ~/.aider-watch.env
EOF
  exit 1
fi
chmod 600 "$HOME/.aider-watch.env"

# 4. 工作目錄
mkdir -p "$HOME/aider-watch/"{buffer,logs}
touch "$HOME/aider-watch/live.log"

# 5. launchd
DEST="$HOME/Library/LaunchAgents"
mkdir -p "$DEST"
cp "$ROOT/launchd/com.awoooi.aider-flush.plist" "$DEST/"
launchctl unload "$DEST/com.awoooi.aider-flush.plist" 2>/dev/null || true
launchctl load -w "$DEST/com.awoooi.aider-flush.plist"
launchctl list | grep aider-flush || { echo "launchd load failed"; exit 2; }

# 6. doctor
aider-watch doctor || { echo "doctor failed — fix env and re-run"; exit 3; }
echo "✓ install OK"
```

- [ ] **Step 3: Commit**

```bash
chmod +x scripts/aider_watch_client/scripts/install.sh
git add scripts/aider_watch_client/scripts/install.sh scripts/aider_watch_client/launchd/
git commit -m "feat(client): install.sh + launchd flush plist (5min)"
```

# Phase C: 整合驗收（3 tasks）

## Task C1: E2E Happy Path（Mac → awoooi）

**需要前置**：
- awoooi API 跑起來（K3s 或本機 dev）
- `~/.aider-watch.env` 有 AIDER_API_URL + AIDER_WEBHOOK_SECRET
- K8s Secret 或 env 有 AIDER_WEBHOOK_SECRET 匹配

- [ ] **Step 1: 跑 install.sh**

```bash
cd /Users/ogt/awoooi && bash scripts/aider_watch_client/scripts/install.sh
```

Expected: install OK + doctor 全 ✅

- [ ] **Step 2: 跑一次 aiderw**

```bash
mkdir -p /tmp/aw-e2e && cd /tmp/aw-e2e
git init -q && echo "def f(): return 0" > calc.py && git add -A && git commit -m init -q
aiderw --yes --no-stream --no-pretty \
  --message "fix calc.py f should return 42" --exit
```

Expected: aider 正常跑，terminal 有輸出。

- [ ] **Step 3: 查 awoooi PG 有事件**

```bash
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi -c \
  "SELECT type, ts, payload->>'model' AS model FROM aider_events ORDER BY ts DESC LIMIT 10"
```

Expected: 至少 session_start + session_end 2 筆；若 aider 改了檔有 file_edit 若改 exit=0 無 error。

- [ ] **Step 4: 若 aider 失敗（e.g. 模型 timeout），看 TG**

（若 Step 2 產生 error event）檢查統帥 `@tsenyangbot` DM 有無 incident 告警。

Expected: TG 收到 `[aider] ...` incident 告警；incidents 表有新記錄且 `alert_category='aider_activity'`。

---

## Task C2: E2E Degradation（斷線 → buffer → flush）

- [ ] **Step 1: 拔網路模擬 API 不可達**

```bash
# 方法 A：改 env 指向壞 URL
export AIDER_API_URL="http://127.0.0.1:1/nope"
cd /tmp/aw-e2e && aiderw --yes --no-stream --no-pretty --message "add comment" --exit
unset AIDER_API_URL
```

- [ ] **Step 2: 檢查 buffer 有檔**

```bash
ls ~/aider-watch/buffer/
```

Expected: 至少 1 個 `pending_*.jsonl`

- [ ] **Step 3: 恢復正常 env，跑 flush**

```bash
aider-watch flush
```

Expected: `flushed N events` (N ≥ 1)

- [ ] **Step 4: buffer 應清空，PG 應有記錄**

```bash
ls ~/aider-watch/buffer/                                 # 應為空（或無 pending_*）
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi -c \
  "SELECT count(*) FROM aider_events WHERE ts > now() - interval '10 min'"
```

Expected: buffer 清空；PG count 增加。

---

## Task C3: AI Router Feedback 驗證

- [ ] **Step 1: 灌 fixture：3 場模擬 session（2 成功 1 失敗 elephant-alpha，1 成功 gemini-pro）**

```bash
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi <<'SQL'
INSERT INTO aider_events (session_id, ts, type, host, payload) VALUES
  ('t-e1', now()-interval '2h', 'session_start', 'm', '{"cwd":"/repo/x","model":"elephant-alpha","aider_args":[],"aider_pid":1,"cli_version":"0"}'),
  ('t-e1', now()-interval '2h', 'session_end', 'm', '{"duration_sec":60,"tokens_sent":100,"tokens_received":50,"cost_usd":0,"files_changed":1,"error_count":0,"exit_code":0}'),
  ('t-e2', now()-interval '1h', 'session_start', 'm', '{"cwd":"/repo/x","model":"elephant-alpha","aider_args":[],"aider_pid":2,"cli_version":"0"}'),
  ('t-e2', now()-interval '1h', 'session_end', 'm', '{"duration_sec":120,"tokens_sent":200,"tokens_received":80,"cost_usd":0,"files_changed":0,"error_count":3,"exit_code":1}'),
  ('t-e3', now()-interval '30min', 'session_start', 'm', '{"cwd":"/repo/x","model":"elephant-alpha","aider_args":[],"aider_pid":3,"cli_version":"0"}'),
  ('t-e3', now()-interval '30min', 'session_end', 'm', '{"duration_sec":90,"tokens_sent":150,"tokens_received":60,"cost_usd":0,"files_changed":2,"error_count":0,"exit_code":0}'),
  ('t-g1', now()-interval '20min', 'session_start', 'm', '{"cwd":"/repo/x","model":"gemini-pro","aider_args":[],"aider_pid":4,"cli_version":"0"}'),
  ('t-g1', now()-interval '20min', 'session_end', 'm', '{"duration_sec":50,"tokens_sent":80,"tokens_received":40,"cost_usd":0,"files_changed":1,"error_count":0,"exit_code":0}');
SQL
```

- [ ] **Step 2: 呼叫 ai_router.feedback_from_aider_events()**

```bash
cd /Users/ogt/awoooi && /Users/ogt/.pyenv/versions/3.11.7/bin/python3 <<'PY'
import asyncio
from apps.api.src.services.ai_router import AIRouter

async def main():
    r = AIRouter()
    out = await r.feedback_from_aider_events(days=7)
    print(out)

asyncio.run(main())
PY
```

Expected: `{'elephant-alpha': 0.67, 'gemini-pro': 1.0}` 或相近（success_rate = 2/3 for elephant, 1/1 for gemini）

- [ ] **Step 3: 清理 fixture**

```bash
PGPASSWORD="$AWOOOI_PG_PW" psql -h 192.168.0.188 -U awoooi_rw -d awoooi -c \
  "DELETE FROM aider_events WHERE session_id LIKE 't-%'"
```

- [ ] **Step 4: 最終 commit**

```bash
cd /Users/ogt/awoooi
git add -A
git commit --allow-empty -m "chore(aider-watch): v2 E2E verified 2026-04-20"
```

# Execution Handoff

**Plan complete and saved to** [docs/superpowers/plans/2026-04-20-aider-watch-v2.md](2026-04-20-aider-watch-v2.md)。

兩種執行方式（你選一）：

1. **Subagent-Driven**（spec 原推薦）— 每 task 派 subagent + 兩階段 review。
2. **Inline Execution**（v1 後段我已切成這個）— 主 session 直接跑，效率高但 context 消耗大。

考量本 plan 跨兩個 subsystem（server + client）+ 整合點多（既有 ai_router / incident_service / telegram_gateway 都要對接），建議分段：

- **Phase A 1-5（模型/util/repo/service）**：inline — 單純 code，好測
- **Phase A 6-9（webhook/job/router hook/config）**：**subagent-driven** — 整合點多，需 independent review
- **Phase B 全部 client**：inline — 獨立 module 無耦合
- **Phase C E2E**：inline + 統帥監督

你要照這策略，還是要求全 subagent / 全 inline？
